        이상의 문자(文字) 감각과 매체의 모더니티

        김성수 ( Sung Soo Kim ) 한국비교문학회 2011 比較文學 Vol.55 No.-

        This article begins with an awareness of two. One is to consider the meaning of "letter" sensibility, as expressed in Yi Sang`s text in relation to newspapers and printed media, which constituted modern media in the city of Gyeong-seong [京城] in the 1930`s. The other is to analyze Yi Sang`s dream of writing and of realizing his goals through the letter expression. Therefore, the objective of this article is to investigate the unique ideas about letters and the meaning of the expressions in the literary texts of Yi Sang, who omnidirectionally participated in the so-called "modernity of media," as he drew figures, blueprints, and illustrations and worked as a magazine editor and literary coterie within modern Korean literature in the 1930`s. On the basis of this investigation, we tried to clarify the patterns in Yi Sang`s dreams of writing. Yi Sang`s unique ideas about letters were incorporated into his works in various forms and expressed through his original literary language. Moreover, his ideas had a sociocultural impact at that time beyond the function of delivering literary meanings. In his essay, "Lingering Impressions of a Mountain Village," he expressed the natural mood that sprang up from rural society by replacing with metaphoric language acquired fromand sensitized by "urban emotions." Hence, various aspects of Yi Sang`s literature constituting the so-called "rhetoric of city" were patterned by reflecting urban phenomena in visual forms in many parts of his works. The metaphoric system of the "rhetoric of city" established the unique metaphor in the viewpoint of the new modernity by the emotions and senses of those living in a city in the 20th century, saying good-bye to the senses of the 19th century. The characteristic elements of Yi Sang`s literature in the area of Korean literature in the 1930`s, which resulted from various forms of letters and their application to literary works, can ultimately be considered ventriloquial reactions to the speed of the capitalistic society that was changing rapidly, as well as to the disturbance of time and the entanglement of space in the changing process. This is a key factor in Yi Sang`s literature as well as the novel writing pattern that advocated the autonomy of art as "objectless writing`" based on the letter sensibility and the sign game method. Moreover, the new form of literature realized by Yi Sang`s letter sensibility and his literary world still requires an interpretation from a novel point of view, in the sense that it was an abstract painting that expressed the uneven consciousness of those living in a city, generated from the regulatory system of capitalistic reason that was rapidly expanding in the urban space of Gyeong-seong in the 1930`s.

        역삼투 법을 이용한 유기물의 분리 : 셀루로오즈 아세테이트 및 PVA 막의 경우

        김성수,장호남,유화원 한국화학공학회 1983 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.21 No.4

        수측 온도 60℃에서 처리한 cellulose acetate 막(CA-I), 90℃에서 처리한 cellulose acetate 막(CA-II) 그리고 formalin으로 가교결합시킨 PVA막을 사용하여 100기압하의 연속식 조업 조건에서 수용액상의 여러 유기물들의 투과 거부도(rejection)및 용액 투과량(solution flux)을 조사하였다. CA-I, CA-II와 PVA막은 1% NaCl용액에 대해 4%, 12% 및 0%의 투과 거부도와 1700ℓ, 210ℓ, and 290ℓ/m²·day의 투과량을 보였다. 알콜류의 경우 투과 거부도는 일반적으로 낮았으며 이는 아마 물과 유사한 성질 때문으로 생각되며 메타놀, 에타놀, 이소푸로파놀의 순서로 투과 거부도는 증가하며 투과량은 줄어 들었다. 각종 당류와 아미노산은 NaCl과 유사한 성질을 보였는데 조금씩의 차이는 이들 용질과 용액, 용질과 막과의 상호작용에 의한 것으로 생각된다. 모든 용질중에서 계면 활정세인 TWeen-80은 특별한 성질을 보였는데 CA-I에서 96%의 투과거부도와 540ℓ/㎡·day의 용액 투과량을 보여 막 표면에 dynamic membrane을 형성하는 것으로 보인다. PVA막은 일반적으로 cellulose acetate막에 비해 투과 거부도와 용액 투과량이 다같이 낮았다. Permeabilities and fluxes of many organic solutions were tested under continuous reverse osmosis system at pressure of 100 atm using cellulose acetate membranes shrunk at 60℃(CA-I), 90℃(CA-II) and PVA membrane crosslinked with formalin. CA-I , CA-II and PVC membranes were characterized by rejections of 16%, 96% and 14% and water fluxes of 1,700ℓ, 210ℓ and 290ℓ/m²·day respectively against 1% NaCl testing solution. Alcohols showed lower rejection than other solutes due to the similarity of their chemical properties to water (CA-I, 4% ; CA-II, 12%; PVC, 0%). In the order of methanol, ethanol and i-propanol, gradual rise in rejection and decrease in flux with molecular weight were observed. Various sugars and amino acids were rejected similarly to NaCl even though slight differences in rejections and fluxes were considered to be attributed to the interaction of solute molecules with membranes and solvent. Among all, surfactant Tween-80 showed peculiar behavior that even in CA-I rejections were 96% and fluxes were 540ℓ/㎡day. in this case CA-I membrane behaved like CA-II perhaps due to the formation of dynamic membrane on the surface. The rejections and fluxes by PVA membrane were lower than those by cellulose acetate membranes.

        하구순에 발생한 편평상피암의 치료

        배용찬,황소민,김성호,김성수 大韓成形外科學會 1998 Archives of Plastic Surgery Vol.25 No.2

        The squamous cell carcinoma is the most common cancer of lower lip. Although various treatment methods have been introduced, surgical resection and reconstruction is considered to be the most important medical remedy. We surveyed 11 patients who received the surgery for squamous cell carcinoma on lower lip from January 1992 to December 1997. The survey included the size and location of tumor mass, the presence of lymph node metastasis for a preoperative evaluation, the aesthetic and the performance of lower lip after the operation, the recurrence rate, the complication and the mortality rate. In resectioning tunmor mass, the surgery has to completely remove the mass and meanwhile has to minimize the loss of normal tissues. Also in reconstruction of lower lip, it has to resemble, aesthetically and functionally, the normal lower lip as well. To achieve such s, the pre-excisional frozen biopsy was performed to determine the surgical margins and various reconstructive methods were tried according to the location and size of the defect remained in the lower lip. In the most of clinical cases, appropriate vermillion and nasolabial sulcus were fashioned and they functioned normally in both speech and mastication. As for complications, each case of drooling and macrostomia were reported, There was no mortality from lower lip carcinoma and its recurrence. Due to determination of the safe surgical margin by pre-excisional frozen biopsy and reconstruction by appropriate procedure according to the location and the size of defect, the survey indicates minimized postoperative complications, no recurrence and no mortality as well as aesthetically and functionally adequate lower lip

        표피 성장인자의 국소적용이 인체 표피화에 미치는 효과에 대한 연구

        김현옥,유성종,정승문,김성수 大韓成形外科學會 1993 Archives of Plastic Surgery Vol.20 No.3

        An understanding of the mechanism of healing has increased dramatically during the past decade. The phenomenon of epithelization is important in the normal resurfacing of a donor site or a partial thickness burn wound. This study was conducted to clarify the effect of epidermal growth factor in wound healing of human. Paired donor sites were created in 18 patients who required skin grafting for either burns or reconstructive surgery. One donor site from each patient was treated topically with silver sulfadiazine cream, and the other was treated with silver sulfadiazine cream containing epidermal growth factor(10ug/ml) (Human recombinant epidermal growth factor ; Sigma, St.Louis, Mo). The donor sites were photographed daily, and healing was measured with the use of planimetric anlysis. The donor sites treated with silver sulfadiazine containing epidermal growth factor had an accelerated rate in all 18 patients as compared with that in the paired donor sited treated with silver sulfadiazine alone. Combining data from all patients demonstrated reduced the average time to 100% healing by approximately 2 to 3 days (p<0.01). Light and electron microscopical study of biopsy specimens taken from the centers of donor sites three days after the onset of healing supported these results. In conclusion, epidermal growth factor accelerates the rate of healing of partial thickness skin wound.

        김성수,정성석 全北大學校 基礎科學硏究所 1994 基礎科學 Vol.16 No.-

        The Analysis of Variance(ANOVA) is a general tool for analysing desinged experiments. Among the many statistical softwares on ANOVA available in personal computers, we will review SAS(version 6.04), SPSS/PC+(version 4.0) and S-PLUS(version 2.0). SAS and SPSS/PC+are popular data analysis systems, and S-PLUS is an interactive graphical data analysis system. Statistical graphics give many informations aobut the main effects and the interaction effects in experimental data, and diagnostics about the model design. S-PLUS is very useful in these respects. Combining the analysis by SAS ans SPSS/PC+ with graphical displays of S-PLUS will give good interpretation of designed experiments.

        There is a continuously growing demand for usable channels that are necessary for communication between mobile users and the base stations of cellular radio networks. However, the number of usable channels is very limited. The objective of this paper is to develop a hybrid method of evolution program(EP) and frequency exhaustive assignment(FEA) for the NP-hard channel-assignment problems to find an optimal channel assignment for minimum interference among the channels within a limited time.
